I Need Cheat Codes for My Niece: Playstation 2-tombraider Angel of Darkness?

Ten points to the person who can give me the cheat codes for skipping levels and any other cheat codes. My niece is stuck on a level where she's fighting Boaz ( that great big gross bug ) and is stuck on that level. She's been stuck on that level now for over a month and cannot beat Boaz no matter how hard she tries. Please give the codes for the level skip and any other codes. Thank you very much!!
